I think I'll have a "nvme_dev_notify" similar as "handle_notify"

static void nvme_dev_notify(EventNotifier *e)

{
    ....
}

But then how can I know this notify is for cq or sq?

virtio-blk has a single queue, so it has a single EventNotifier. Your code using multiple EventNotifiers is fine, you can use aio_set_event_notifier multiple times on the same iothread.
